The Nodes of Ranvier

Question

The nodes of Ranvier
A) are located along the postsynaptic membrane.
B) increase the speed of the action potential.
C) synthesize the neurotransmitter acetylcholine.
D) store ACh in tiny vesicles.

Accepted Answer

The nodes of Ranvier are gaps in the myelin sheath that increase the speed of the action potential by allowing it to jump from one node to the next. They are not located along the postsynaptic membrane, synthesize neurotransmitters, or store ACh.
